Description

一种传输数据方法和设备
本申请要求在2016年07月18日提交中国专利局、申请号为201610566411.6、申请名称为“一种传输数据方法和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，特别涉及一种传输数据的方法和设备。
背景技术
随着无线通信***的发展，终端类型和业务类型多样化，终端省电、节约网络资源和满足各种业务类型的需求并存。为了同时保证终端省电和快速数据传输，引入一种终端状态非激活(inactive)态，这种状态下终端保持核心网连接，但不进行空口连接态的常规操作(如切换、上行定时更新、无线链路监控等)，不分配直接用于空口传输的终端标识(如小区无线网络临时标识符(Cell Radio Network Temporary Identifier，C-RNTI))，因此不能直接进行空口调度传输。
Inactive状态下，网络侧为终端分配一定区域内有效的无线接入网(Radio Access Network，RAN)标识，该标识用于在inactive状态下识别终端，可以用于网络侧查找终端或终端主动发起上行接入时用该标识作为身份识别进入连接态，可以称为inactive终端标识(UE ID)，也可以称为用于恢复连接的UE ID(resume UE ID)。该标识只在包含多个小区或多个eNB的一定区域内有效，如果超过该区域，终端需要更新inactive UE ID。
Inactive状态下的UE在某个特定的区域内移动是不需要通知基站的，因此，收发数据的基站无法与Inactive状态下的UE进行数据传输。
综上所述，目前收发数据的基站无法与Inactive状态下的UE进行数据传输。

具体实施方式
本申请实施例在终端从连接态转到非连接态后，将所述终端的上下文发送给目标区域内的第二网络侧设备，可以使所述第二网络侧设备根据收到的上下文与所述终端进行数据传输。由于本申请实施例非连接态的终端对应的区域中的基站能够获得终端的上下文，从而可以与非连接态的终端进行数据传输，以使非连接态的终端可以更加快速的传输数据； 进一步提高传输的性能。
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部份实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
如图1所示，本申请实施例传输数据的***包括：第一网络侧设备10和终端20。
第一网络侧设备10，用于在终端从连接态转到非连接态后，确定所述终端的上下文；将所述终端的上下文发送给目标区域内的第二网络侧设备，以使所述第二网络侧设备根据收到的上下文与所述终端进行数据传输；
处于连接态的终端20，用于接收来自第一网络侧设备的进行状态切换的指示；从连接态切换到非连接态，以使所述第一网络侧设备将所述终端的上下文发送给目标区域内的第二网络侧设备，便于所述第二网络侧设备根据收到的上下文与所述终端进行数据传输；
在实施中，所述第二网络侧设备根据收到的上下文与所述终端进行数据传输时，这里的终端可以保持在非连接态，并进行传输数据；也可以先进入连接态，然后再传输数据。也就是说，与第二网络侧设备进行数据传输的终端可以是处于非连接态的终端也可以是处于连接态的终端。
其中，所述第一网络侧设备为所述终端从连接态转到非连接态之前最后接入的网络侧设备，所述目标区域为非连接态的终端对应的区域。
比如终端初始接入网络侧设备A，之后切换到网络侧设备B，并在切换到网络侧设备B之后从连接态转换到非连接态，则网络侧设备B就是终端从连接态转到非连接态之前最后接入的网络侧设备。
对于每个非连接态的终端，网络侧都会为非连接态的终端分配一个非连接态终端标识(inactive UE ID)，该inactive UE ID对应一个区域，在该区域内终端移动时不需要切换等操作。
本申请实施例的目标区域就是终端的inactive UE ID对应的区域。
其中，第一网络侧设备可以指示终端从连接态转换到非连接态。下面列举几种。
方式一、所述第一网络侧设备根据所述终端的用户面数据判断是否让终端进行状态切换；
在确定需要切换到非连接态后指示所述终端进行状态切换。
比如：所述终端没有用户面数据，可以将UE切换到非连接状态；反之如果所述终端有用户面数据，则不对UE进行状态切换。
方式二、终端在确定需要进行状态切换后会向第一网络侧设备发送切换到非连接态的请求；
相应的，所述第一网络侧设备在收到来自终端的切换到非连接态的请求后，指示所述终端进行状态切换。
比如终端可以根据自身是否有数据要发送确定是否进入非连接态，即如果没有有数据要发送，则确定进入非连接态；反之，确定不进入非连接态。
上述方式一和方式二也可以结合使用，即第一网络侧设备在确定终端需要切换且收到终端的请求后指示终端进行状态切换。
需要说明的是，上述两种方式只是举例说明，任何能够指示终端进行状态切换的方式都适用本申请实施例。
在实施中，针对不同的第二网络侧设备，第一网络侧设备将所述终端的上下文发送给目标区域内的第二网络侧设备时可以有不同的发送方式：
发送方式一、所述第一网络侧设备通过网络侧设备间的接口将所述终端的上下文发送给目标区域内的第二网络侧设备。
发送方式二、所述第一网络侧设备通过核心网将所述终端的上下文发送给目标区域内的第二网络侧设备。
上述两种发送方式可以参见图2。
如图2所示，本申请实施例第一网络侧设备将所述终端的上下文发送给目标区域内的第二网络侧设备的示意图中，UE和第一网络侧设备连接。

对于目标区域内与第一网络侧设备之间有网络侧设备间的接口的第二网络侧设备，所述第一网络侧设备通过网络侧设备间的接口将所述终端的上下文发送给目标区域内的第二网络侧设备。
在实施中发送方式一和发送方式二还可以结合使用，即对于目标区域内与第一网络侧设备之间有网络侧设备间的接口的第二网络侧设备，所述第一网络侧设备可以分别通过网络侧设备间的接口和核心网将所述终端的上下文发送给目标区域内的第二网络侧设备。
需要说明的是，上述两种发送方式只是举例说明，只要第一网络侧设备能够将上下文发送给目标区域内的第二网络侧设备的发送方式都适用本申请实施例。
可选的，所述第一网络侧设备将所述终端的全部或部分上下文发送给目标区域内的第 二网络侧设备。
由于发送上下文的目的是为了网络侧设备可以与终端进行数据传输，所以网络侧设备只需要上下文中能够正确解析上行数据并路由到核心网的相关信息即可，所以第一网络侧设备可以只将上下文中的这些信息发送给目标区域内的第二网络侧设备。
可选的，第一网络侧设备在终端从连接态转到非连接态后，可以判断是否满足上下文发送条件，并在确定满足上下文发送条件后将所述终端的上下文发送给目标区域内的第二网络侧设备。

这里的快速数据传输包括非连接状态下的数据传输和/或进入到连接状态的数据传输。
在实施中，若所述上下文发送条件包括上下文发送条件一，且所述第一网络侧设备是所述终端初始接入的网络侧设备，则所述第一通知是所述终端发送的；

上下文发送条件二、接收到终端进入非连接态后需要发送上下文的第二通知。
具体的，所述终端在初始接入到网络侧设备后，向所述网络侧设备发送终端进入非连接态后需要发送上下文的第二通知；
相应的，如果第一网络侧设备接收到终端进入非连接态后需要发送上下文的第二通知，则确定满足上下文发送条件。
若所述上下文发送条件包括上下文发送条件二，且所述第一网络侧设备是所述终端初始接入的网络侧设备，则所述第二通知是所述终端发送的；
若所述上下文发送条件包括上下文发送条件二，且所述第一网络侧设备不是所述终端初始接入的网络侧设备，则所述第二通知是其他网络侧设备发送的。
比如终端在初始接入网络侧设备之后发生切换过程，则在切换过程中，源网络侧设备通知目标网络侧设备该终端进入非连接态后需要发送上下文。即如果终端在初始接入网络侧设备的时候通知网络侧设备终端进入非连接态后需要发送上下文，需要保证终端每次切换后目标基站都能得到该通知。
上下文发送条件三、根据终端的终端信息确定需要将所述终端的上下文发送给第二网络侧设备。
比如UE的业务类型需要支持低时延的快速数据传输，则需要将所述终端的上下文发送给第二网络侧设备；
还比如UE处于高速移动，需要将所述终端的上下文发送给第二网络侧设备。
